Well if you are looking to add some size don't forget to eat lots of good calories greens, and lots of meat. There is also the GOMAD diet if you can find some good quality milk where you are. Don't be too concerned with the not making it to the next level this time. Your body is just adjusting at it own pace. I bet if you will pass to the next level soon. Good luck with your training! Oh man you made me do math 1 stone = 14lbs so 11st 3lbs = 157 lbs. Once suggestion as far as diet goes try not to just eat everything under the sun. This leads to dirty bulking and can have ill effects on your body composition and heart health and lots of other things. If you are gonna eat alot make sure it is healthy eating with lots of water.

Sorry I missed your post on the 3rd. Had I seen it I would have made a suggestion to do your pullups on the rings if you have them. The only reason I state this is because they allow for different movement patterns. Also good luck on your L4D3!
